Cytotoxic metabolites from Callyspongia siphonella display antiproliferative activity by inducing apoptosis in HCT-116 cells

Abstract

Several metabolites were isolated from the marine sponge Callyspongia siphonella. Sipholenol A and sipholenol L exhibited effective cytotoxicity against HCT-116 cells. The observed cytotoxicity involves induction of cellular apoptosis. <b>Abbreviation used:</b> A549 (human lung carcinoma), Caco-2 (Human ColonCarcinoma), CHCl3 (Chloroform), HCT 116 (Human Colon Carcinoma), HepG2 (Liver Hepatocellular Carcinoma), HT-29 (Human Colorectal Adenocarcinoma), MCF-7 (Michigan Cancer Foundation-7; Human Breast Adenocarcinoma), MeOH (Methanol), NMR Nuclear Magnetic Resonance), PBS (Phosphate Buffered Saline), PC-3 (Human Prostate Cancer), PTLC (Preparative Thin Layer Chromatography), RPMI-1640 (Roswell Park Memorial Institute medium), TLC (ThinLayer Chromatography).
